USB Audio

Your system supports audio input and output sources through USB connections. When enabled, non-USB audio connections aren’t supported.

Using USB and Bluetooth Headsets

You can use USB and Bluetooth headsets with your system (Bluetooth headsets require a USB adapter).

When connected, you can control your headset audio but not the system audio (such as mute or volume control).

Only headsets with the following specifications are supported:

  • 48 kHz sample rate
  • Dual channels
  • 16-bit pulse-code modulation (PCM)

Using the Shure IntelliMix P300

You can connect a Shure IntelliMix P300 audio conferencing processor to your G7500 or Studio X50 system using a USB-A port (USB-C isn’t supported).

Note the following when using this audio processor:

  • Once connected to the system, the processor handles all audio.
  • You can’t use speakers and microphones that aren’t connected to the processor.
  • The video system automatically disables its internal echo cancellation processing.

Using the EagleEye Cube USB Camera Microphone

With a G7500 system, you can use the Poly EagleEye Cube USB camera as a microphone if you don’t connect other microphones to the system.

Enable USB Audio

USB audio connections (for example, a USB headset) don’t work by default.


  1. In the system web interface, go to Audio/Video > Audio > General Audio Settings.
  2. Select the Enable USB Audio check box.
